Left-hander Wei-Yin Chen (pictured) was on his way to his second strong performance in a row when he grabbed at his side and exited Sunday's game with a right oblique strain. That's very bad news for a team that already has called on four Triple-A starters to fill in the fifth slot in the rotation and replace injured Miguel Gonzalez. It was a tough week already, after so-so outings by Jason Hammel, Freddy Garcia and Steve Johnson, and that was reflected in the combined numbers. The rotation posted a 2-2 record with a 6.03 ERA and averaged just five innings per start. Even though the team managed to go 4-2 in those games, this is starting to get scary.

The Orioles have designated Brad Bergesen for assignment, according to a source.
The move has not been made official, but the club needs to make a move by tonight because infielder/outfielder Bill Hall has been called up from Triple-A Norfolk.
The 26-year-old Bergesen, a former fourth-rounder in 2004 by the Orioles, is 17-24 with a 4.68 ERA in 83 games, 59 starts, for the Orioles in his career.
He did not make the team out of spring and has been in Norfolk, where he is 1-2 with a 5.13 ERA in eight games (six starts).
